MEGASQUIRT TUNE UPDATE

Description

Have a MegaSquirt in your vehicle? Need your current tune updated? Send us your current tune and a log(s) and we will update your tune — fueling, ignition, and any other minor corrections that may be needed. For full MS tuning for new installs, please see our Full MegaSquirt Tuning service

This requires your vehicle to be already running, and we will need the following parameters logged: (the parameters may be worded differently depending on your MS version and software)

• Time
• Vehicle Speed (if equipped with VS sensor)
• RPM
• Air to Fuel Ratio (or Lambda value)
• Manifold Air Pressure*
• Throttle Position*
• Load

* Only necessary where applicable.

The more data you can log, the more we can work with, but logging too many parameters can slow down logging frequency. It’s best to keep logged parameters fewer than 20.
